This MATLAB script incorporates edits from 3 files (biomass_edits_final.xls, edits_additions_or_modifications_final.xls, and reaction_delete_edits_final.xls) into the Plata et al. reconstruction (plata_orig.xml) to generate our reconstruction iPfal17 and genes_used_by_model.csv.
This MATLAB function identifies genes in model associated with reactions. Necessary for test_exp_knockouts_careyBMCG.m.
This MATLAB script identifies essential genes and lethal enzyme inhibition in the model. It also compares to predictions in Plata et al. 2010. It requires the model from model_curation_careyBMCG.m and exp_predictions_KOs_wPlata.xls. It is used in generating Table 4 and Suppl. Table 7. It also generates essential_genes.csv for Plasmogem_careyBMCG.R.
This MATLAB script implements Network Expression Analysis using MADE (Jensen and Papin, 2011) and iPfal17. Expression files (cambodia.csv and vietnam.csv) from DEGs_careyBMCG.Rmd and model from model_curation_careyBMCG.m are used. It writes the following files used in figures_careyBMCG.R:
GeneRxnsSubsytems.xls
figure2_prep.xls
gene_states_c.csv
gene_states_v.csv
This MATLAB script evaluates a model on 11 metabolic tasks (see Table 3). Some tasks are meant to fail. All are based on experimental literature or COBRA standards. It requires the model from model_curation_careyBMCG.m.
This R markdown script was used to calculate differential expression of ring-stage samples from GSE59097. This script inputs preprocessed and normalized expression data to calculate differential expression.
The following files are required:
mok_accession_data_removed_ifNoRNA_orIfGam_orIfNoPCH.csv (from supplemental table in Mok et al. 2015)
GPL18893.txt (acquired from GSE59097)
blast_output_pf_e0001 (generated from blast_script_careyBMCG.rtf)
genes_used_by_model.csv (acquired from model_curation_careyBMCG.m)
Pfalciparum3D7_GeneAliases.csv (acquired from PlasmoDB.org)
The following files are generated:
cambodia.csv
vietnam.csv
This R script was used to generate random forest classifiers of metadata and expression data associated with GSE59097. This script inputs preprocessed and normalized expression data, uses requires files mok_accession_data_removed_ifNoRNA_orIfGam_orIfNoPCH.csv, GPL18893.txt, blast_output_pf_e0001, and generates Suppl. Figure 2 and variable_importance_expression.csv.
This R script is used to generate Suppl. Table 6. This script compares iPfal17 predictions (File essential_genes.csv) to P. berghei essentiality results generated by the PlasmoGEM team (in file plasmogem.csv which is subsetted into essential_plasmogem.txt and dispensible_plasmogem.txt).
Note: used dictionary from DEGs_careyBMCG.R
This R script generates Figures 1 and 2 and Suppl. Figures 1, 3 and 4 for Carey et al. BMC Genomics. To generate Figure 1, functions and files from DEGs_careyBMCG.R are needed. Figure 2 requires figure2_prep.txt and edits.csv. Suppl. Figure 1 requires cambodia.csv and vietnam.csv. Suppl. Figure 3 requires gene_states_c.csv and gene_states_v.csv. Suppl. Figure 4 requires GeneRxnSubsystems.txt and figure2_prep.txt.
This text file lists commands to reannotate platform probe IDs. Probe sequences must first be reverse complemented. It will generate blast_output_pf_e0001.
